Side Jobs other than Gigolo

I've been trying to figure out what I could do on the side to make a little extra money to feed my bike addiction. I have a job that offers lots of sitting around time. I'm on call and have lots of time at home but I have to be very flexible with my schedule. I was wondering if anyone has any good ideas or insight into what I should do to make some more dough.

since you've excluded it from discussion, I assume you're already whoring out your "services" and it doesn't provide enough?

I suggest hiring yourself out to local high school students to make beer runs. I hear that can be quite lucrative, but I suggest you choose the wealthy neighborhoods and aim for the clientele willing to pay for your service.

don't try posing as a wino in the back alley, because those punks WILL stiff you if given half a chance.

You can escort bikers through the rough neighborhoods, charge 20 bucks one way. My other idea is to buy full half link chains and sell them individually (links) on ebay at 2 bucks a pop, will work. The competition is 3 bucks plus 2 bucks shipping. Or you can fix bikes on the side, craigslist post.
